Mananalu Fights Plastic Pollution

Introduction to Mananalu and its Mission to Reduce Plastic Pollution

Jason Momoa launched Mananalu in 2019 with a clear goal: challenge the bottled-water industry to move away from single-use plastic. The Hawaiian water brand began with aluminium bottles and a “buy one, remove one” programme that funded the removal of plastic bottles from the ocean. This initiative has resulted in the extraction of over 6 million plastic bottles from the ocean, significantly contributing to the reduction of plastic pollution.

In January 2025, Mananalu relaunched as Mananalu Powered by Boomerang Water, introducing on-site bottling machines that can sanitise, rinse, fill and cap 400 to 500 reusable aluminium or glass bottles every hour. This innovative technology marks a significant shift in the company's operations, aiming to eliminate single-use water bottles and reduce carbon emissions by 95%.

The Impact of Plastic Pollution and the Need for Sustainable Solutions

Plastic pollution has become a pressing global issue, with millions of tons of plastic waste ending up in oceans and landfills each year. The bottled water industry is a significant contributor to this problem, with billions of single-use plastic bottles being produced and discarded annually. Mananalu's approach to reducing plastic pollution is not only beneficial for the environment but also sets a precedent for other companies to follow.

The Refill System: A Game-Changer in the Bottled Water Industry

The new Mananalu Powered by Boomerang Water system is roughly the size of a hotel ice maker. It connects to a local municipal water source, purifies the water through a proprietary filtration process, and fills reusable bottles on site. The machines can process 400 to 500 aluminium or glass bottles per hour, or up to 4,000 bottles a day, making it a highly efficient and sustainable solution.

The process is designed to be circular. After a guest finishes drinking, the bottle is returned to the machine, where it is sanitised, rinsed, filled, capped, and sealed for the next use. This closed-loop model removes the need for disposable bottles and reduces the transport, packaging, and waste associated with conventional bottled water.

Benefits of the Refill System for the Environment and Businesses

• Reduces single-use water bottles, thereby decreasing plastic pollution
• Decreases carbon emissions by 95%, contributing to a more sustainable future
• Provides a cost-effective way to offer clean drinking water with minimal waste, benefiting businesses and the environment

Partnership with Hospitality Brands: A Step Towards a More Sustainable Future

Mananalu began its rollout on Oahu with four hospitality partners: The Twin Fin Hotel, Romer House Waikiki, Kaimana Beach Hotel, and Alohilani Resort Waikiki Beach. These hotels will use the refill system to provide guests with purified water in reusable containers rather than single-use plastic bottles, setting an example for the hospitality industry to adopt more sustainable practices.

Stephen Hinck, area managing director and general manager of The Twin Fin, expressed the hotel's honour in being the first Oahu hospitality partner to implement the technology. He described the partnership as part of the hotel’s commitment to celebrating Hawaii’s natural resources and encouraging guests, staff, and the local community to adopt a more mindful approach to water consumption.

Future Plans: Expanding the Reach of Sustainable Water Solutions

Mananalu is now working with hospitality brands, local businesses, and schools in Hawaii to eliminate single-use water bottles and help the state regain independence from mainland bottled-water shipments. The company also plans to scale the technology through global corporate partners, aiming to make a significant impact on the reduction of plastic pollution worldwide.

Jason Momoa emphasized that the aluminium-bottle phase was intended to push the drinking-water industry to change, but he argued that the next step needed to go further. “We pushed the drinking water industry to change with our aluminum bottles, and now it’s time to push again,” he said, highlighting the partnership with Boomerang Water as a crucial step towards eliminating waste and environmental impact in the pursuit of healthy water.

Implications for Readers in India: Adopting Sustainable Practices

The issue of plastic pollution is not limited to any one region; it's a global problem that requires collective action. Readers in India can draw inspiration from Mananalu's innovative approach and apply similar principles in their daily lives. By choosing products with minimal packaging, supporting companies that adopt sustainable practices, and advocating for environmental conservation, individuals can contribute to the reduction of plastic pollution.

What to Watch Next: The Evolution of Sustainable Water Solutions

As Mananalu continues to expand its reach and impact, it will be interesting to see how other companies in the bottled water industry respond to the challenge of reducing plastic pollution. The development of new technologies and innovative solutions will play a crucial role in shaping the future of sustainable water practices. By staying informed and engaged, readers can support the transition towards a more sustainable and environmentally conscious world.
